We got here by way of an infographic I was reading that talked about islands around the world where specific animals live en masse. Among the animals listed was the tree lobster. I legitimately said, out loud, “what the hell is a tree lobster?” Because seriously? Tree lobster?
It turns out that tree lobsters are not the awesome thing I had created in my imagination; they’re a species of stick insect that live on Lord Howe Island in Australia.
The tree lobster had once been used as fishing bait, but were thought to have been eaten into extinction by the early 1920s by black rats introduced to the island when the S. S. Makambo ran aground in 1918. But it turns out they didn’t actually go extinct; they just went into hiding for a couple generations before being rediscovered in 2001.*
An adult can grow to 15cm (roughly 6″) in length — which is terrifyingly large for a stick insect, thank you — and looks like it’s got a lobster’s exoskeleton.
*This is called the Lazarus Effect.
